Null Pointer exception when executing data flow from activity
When executing a data flow from an activity , its failing because of Null Pointer Exception at the "DataFlow-Execute" step.
I have configured the source of the data flow as abstract , as it should take the step page of the activity as source. The same data flow when i execute stand-alone by changing the source to a Report definition (which opens the same record as the activity), it works fine.
Attached the tracer extract and screenshots of the activity and data flow.
